(8) (123 points.) Which is greater your answer. Earth's pull on the you, or your pull on Earth? Explain (9) (3 points.) With what force would you need to kick a 10 kg ball in order for it to accelerate just as much as a kicked 1 kg ball? (Give the relative force - that is, the ratio of forces and justify your answer.) (10) (3 points.) What is the acceleration of Earth produced by the Moon's gravity, relative to the acceleration of the Moon produced by Earth's gravity? (You can give a ratio of masses and/or any other relevant variables, using symbols - no actual numbers need to be inserted.) (11) (3 points.) In Newton's version of Kepler's third law, is Kepler's "constant" actually a constant? If not, on what does it depend? (12) (3 points.) What is the orbital period of a planet orbiting 6 AU from a star that is 36 times as massive as the Sun? (Hint: Consider Newton's version of Kepler's third law. Use ratios!)
